This plugin will remove the DRM from Kobo ebooks download on Mac or Windows using the Kobo desktop application, or from Kobo ebooks on an attached E-Ink Kobo reader (but not a Kobo Arc or Kobo Vox). If both are available, ebooks will be read from the attached E-Ink Kobo reader. To import from the desktop application, unplug the Kobo reader.
Installation
------------
Open calibre's Preferences dialog. Click on the "Plugins" button. Next, click on the button, "Load plugin from file". Navigate to the unzipped DeDRM_tools folder, find the file "obok_plugin.zip". Click to select the file and select "Open". Click "Yes" in the "Are you sure?" dialog box. Click the "OK" button in the "Success" dialog box.
Note: This plugin requires the "wmic" component on Windows. On Windows 10 and below this will be available by default, on Windows 11 it needs to be explicitly enabled. Make sure that on your Windows 11 machine, under Settings -> System -> Optional features -> Add an optional feature -> View features, "WMIC" is enabled / activated, otherwise this plugin may not work correctly.
No customization is required, except choosing which menus will show the plugin. Although the ability to enter a device serial number is given, this should not need to be filled in, as the serial number should be picked up automatically from the attached Kobo reader.
Using the plugin
----------------
Select the plugin's menu or icon from whichever part of the calibre interface you have chosen to have it. Follow the instructions in the dialog that appears.
Troubleshooting
---------------
If you find that the DeDRM plugin is not working for you (imported ebooks still have DRM - that is, they won't convert or open in the calibre ebook viewer), you should make a log of the import process by deleting the DRMed ebook from calibre and then adding the ebook to calibre when it's running in debug mode. This will generate a lot of helpful debugging info that can be copied into any online help requests. Here's how to do it:
- Remove the DRMed book from calibre.
- Click the Preferences drop-down menu and choose 'Restart in debug mode'.
- Once calibre has re-started, import the problem ebook.
A log will appear that you can copy and paste into a GitHub issue at noDRM's repository, https://github.com/noDRM/DeDRM_tools/issues . You should also give details of your computer, and how you obtained the ebook file.
